[HACKERS] [GSoC] kmedoids status report

Hi! Here is a report of what has been discussed yesterday on IRC. The kmedoids module now seems to work correctly on basic datasets. I've also implemented its variants with different seeding methods: random initial medoids, and initial medoids distributed among the points (similar to kmeans++ [0]

Hi! Here's my report for week 5. Week 5 - 2014/06/22 This week has been full of debugging of the main SQL function. The previous week, I had been able to come up with a working function to compute a medoid for a given group of points, but since then I've struggled to integrate it with the rest o

ally, for the coming week, I'll finish debugging k-medoids, write all the secondary functions (e.g. random inital medoids), and write the doc. Regards, Maxence A. -- Maxence Ahlouche 06 06 66 97 00

Re: [HACKERS] [GSoC] Clustering in MADlib - status update

x27;t know yet if I'll be on time by then or not. It will depend on how fast I can get kmedoids working, and how fast I'll go once I'm full time GSoC. Finally, don't hesitate to tell me if you think my decisions are wrong, I'm glad to learn :) [0] http://git.viod.eu/viod/
